摘　　要：室内环境复杂性以及建筑物对信号的干扰使得GPS等室外定位无法精准作用于室内环境,因此提出一种混合室内定位系统,提高定位精准度,可较为直观地反映出定位地点的位置信息,一定程度上减少了定位所需时间。本文通过在一处居所的定位实验简单研究了混合定位的实现方式以及影响定位精度的因素,定位精度受数据库记录点密度、信号衰减系数、室内环境的变动等因素影响。The complexity of the indoor environment and the interference of buildings on the signal make outdoor positioning such as GPS unable to accurately act on the indoor environment.Therefore,this paper proposes a hybrid indoor positioning system to improve the positioning accuracy,which can more intuitively reflect the location information of the location and reduce the time required for positioning to a certain extent.This paper simply studies the realization method of hybrid positioning and the factors that affect the positioning accuracy through the positioning experiment in a residential building.The positioning accuracy is affected by the density of points recorded in the database,the signal attenuation coefficient,the change of indoor environment and other factors.
